Millions of people in America suffer from anemia, a reduction in either the number of red blood cells or the amount of hemoglobin in the blood.
Nutritional anemia is directly caused by a lack of sufficient quantities of all the nutrients - iron, folic acid and vitamin B12.
The World Health Organization has defined nutritional anemia as a condition in which the hemoglobin content of the blood is lower than normal as a result of deficiency of one or more essential nutrients regardless of the cause of such deficiency.
There are four types of nutritional anemia:
*Iron deficiency anemia
*Megaloblastic anemia’
*Pernicious anemia
*Anemia of chronic and inflammatory disease
Nutritional anemia was considered to be large component of global anemia prevalence, and iron deficiency anemia was considered the most common cause of nutritional anemia.
There are numerous ways in which illness can result in deficiencies of iron, folate and vitamin B12, the main causes of the nutritional deficiency.
Blood loss, common to many illness, is a primary cause of iron deficiency. It affect the poorest segment of the population, particularly in areas of the world where malnutrition is predominant and the population is exposed to water related infected.
Macrocytic anemia include megaloblastic anemia or folate deficiency and pernicious anemia or vitamin B12 deficiency. The presence of macrocytic red blood cells requires evaluation both of both folate and vitamin B12.
